A fact family consists of related addition and subtraction equations that use the same numbers. For the number 6, one possible fact family could be 6 + 2 = 8 and 8 - 2 = 6. The related subtraction equations would be 8 - 6 = 2 and 2 + 6 = 8. Thus, the fact family can be represented as 6, 2, and 8.
Yes, a system can, in fact, have exactly two solutions.
No, a system of two linear equations cannot have exactly two solutions. In a two-dimensional space, two linear equations can either intersect at one point (one solution), be parallel (no solutions), or be the same line (infinitely many solutions). Therefore, it is impossible for a system of two linear equations to have exactly two solutions.
There cannot be such a family because of self-reference. It is similar to the Russell paradox (named after Bertrand Russell). As soon as you have a fact family with only two facts, you have added a third fact. The third fact is that is that the fact family had only two facts. That then makes it a family with three facts. Which means it is no longer a fact family with only two facts. So the third fact is no longer correct. And so it does not have three facts. Which means it has only two facts and you will keep looping round and round forever!
y = mx + b y = mx + c c does not equal b the two equations are parallel and will therefore never intersect with one another.

They are simultaneous equations.
A system of equations.
Maxwell's equations contain two scalar equations and two vector equations. Gauss' law and Gauss' law for magnetism are the scalar equations. The Maxwell-Faraday equation and Ampere's circuital law are the vector equations.
Two equations are independent when one is not a linear combination of the other.

Equations can be tricky, and solving two step equations is an important step beyond solving equations in one step. Solving two-step equations will help introduce students to solving equations in multiple steps, a skill necessary in Algebra I and II. To solve these types of equations, we use additive and multiplicative inverses to isolate and solve for the variable.
